The exhaust gas recirculation system brings some exhaust gas back into the engine's air intake. There are many threads about the EGR system...
Good idea. Hopefully it's just a speed sensor. Off topic, but have you cleaned your EGR system?
To get to a diagnosis, you'll need the error codes. Hopefully your code reader will work. If not, the codes can be made to flash, by jumpering...
The best thing to do is read the threads here, and learn as much as you can. You'll likely conclude that the EGR system is the Gen-3 Prius's...
Read up on the EGR cleaning threads here. The EGR system (cooler, valve and intake manifold) eventually clogs up and should be cleaned.
How about the EGR cooler, and the intake manifold?
Don't count yourself short. You can do it. A selection of tools (extensions and swivels) and the #8 T socket are needed. Plus, you need the time...
Something in the exhaust system, maybe a heat shield? Search around the site, as there have been some threads about the heat shield/exhaust...
I've never seen the 12-quart boxes. Good find! There's a current Mobil1 rebate offer, but for purchases not at Wal-Mart: 2020 Mobil 1™ Promotion...
I've never had an issue with our solar roof, either head clearance, or with the gaskets. You definitely should check both, closely. I've been in...
Because of the "bucking" and previous misfire code, and with that mileage on an uncleaned EGR system, this is starting to sound like an unusual...
Thank you for pointing these devices out.
Congratulations! Nice picture! With all the maintenance up-to-date, about all you might want to keep in mind would be the 12-Volt battery. It's...
If the spark plugs are original, then replace them, along with cleaning the EGR system (cooler, valve, pipe and intake manifold). Both the plugs...
And the mileage on the car?
Is that mileage correct? It's not a lot, but it sounds like there could is damage due to hitting something, so that a component is bent, and...
...and while you have the intake manifold off, put in a new PCV valve. How many miles are on the car?
Good point, Mendel. If the EGR system has not been cleaned, the number of miles is phenomenal. A great case study!
First, are you up to date with any recalls for your car? You're a little early on the recommend coolant mileage and time, and the coolant is at...
Is that the original 12-Volt battery? If so, don't trust it. If you do require a new hybrid battery, some dealers will sell these around $2200....
